Hi,
I decided to update my Citroen headunit from software SMEG5.1.F.R4 to SMEG5.43.A.R2 thinking that it will sort my bluetooth lag issue.
I have a feeling I didn't do the right thing as now, not only it didn't fix the lag issue but it lost the AUX functionality as well.
Is there anything I can do to fix this now. My VIN is VF7**************[VIN obfuscated, can be read by forum staff]
Thanks a lot.

Re: C4 Picasso 2014 headunit firmware update
Does the head unit still work all the other functions as it should? Is it showing the updated firmware version installed?

Hi,
All the functionalities work the same as before aside from the AUX which stays greyed out whatever I plug into it and play. In regard to Bluetooth, absolutely no improvement: still cutting out mic during most of the calls and the music delay is still about 3sec. The firmware shows SMEG5.43.A.R2 but the Bluetooth software is still the same.
